Steven Tyler won't return to touring because of the pressure, according to his drummer pal Matt Sorum. Tyler officially retired from the road after suffering a fractured larynx which has affected his voice, but fans were hopeful of a return after he got back on stage to perform at the Jam for Janie charity gig at Los Angeles' Hollywood Palladium earlier this month - however, Velvet Revolver star Matt is adamant the one-off performance won't lead to another Aerosmith tour for Steven.
